CLASSIC THICK SOLE – A generous EVA midsole cushions every step so flat doesn't mean stiff.
COMFY THONG STRAP – Soft, skin-friendly straps sit easy between the toes for all-day wear.
WATER-READY – Rinse-and-go foam that dries fast after the beach, pool, or shower.
LIGHTWEIGHT & FLEXIBLE – Bends with your stride, feels barely there on warm-weather days.
TRUE EU SIZING – Listed in EU sizes (36–45). Check the Cloulix Size Guide for US Men/Women conversion before ordering.
The flip flop, perfected. Cloulix™ Swell Flip Flops take the classic warm-weather silhouette and give it a thick, cushioned EVA sole that actually feels good to walk in.
Soft straps sit easy between the toes, and the lightweight foam shrugs off water and dries in a blink — perfect for beach bags, pool decks, and sandy boardwalks. They flex with your stride so “casual” never means “uncomfortable.”
Easy, breezy, and built for sunshine. Sized in EU 36–45 with a free Cloulix Size Guide for US conversion.
Simple sandals, serious comfort — that's the Swell.
